PAD FOR WIND MUSICAL INSTRUMENTS.

Application led March 17. 1925.

In the drawings forming a part of this i application' Fig. l is a central vertical section of my improved pad detached from the key. F ig. 2 is a side elevation of a valve seat With a portion of a key containing my improved pad in section adjacent thereto in open position. Fig. 3 is a like view to Fig. 2 but with the pad on the valve seat. Fig. l is a section on the line 4- 4 of Fig. 3.

Referring to the drawings, my pad comprises a body 5 of pouch form to the back of which is secured a vacuum cup 6, being preferably integral therewith. Body 5 and cup 6 are made of flexible rubber, preferably of high grade to provide the maximum amount of resiliency to the parts. The back of body 5 adjacent to the cup is preferably slightly recessed so that When the pad is positioned in the cup-shaped head 7 of the valve key, cup 6 will be substantially in the plane of the outer portions of the back of body 5 as best shown in Figs. 2 and 3. By constructing the body of the pad of thin high grade rubber and making it of pouch vform thereby forming an air chamber 9, the pad readily conforms to the valve seat 8 and does not stick thereto.

Another advantagejn the use of rubber y arises from the fact that it is not aected by the usual moisture produced by a player in operating a Wind instrument and, there- Serial No. 16,151

fore, the life of the pad is longer than if made of kid or cork which are the materials usually used for valve pads. By the fou mation of the vacuum cup on the back of the body the pad is quickly positioned in the key head and can be quickly removed therefrom.

Having described my invention, I claim:

l. In a Wind musical instrument the coinbination of a key having a cup shaped head,

a pad for said head, said pad being in form e a pouch filled with air, with a vacuum cup on the back thereof, said pouch and cup being fitted into the head to retain their position therein by the suction of the cup on the inner side of the key head.

2. A pad for the keys of Wind musical instruments comprising a pouch shaped body lled with air, and a vacuum cup on the back of said body, said body and cup being formed of rubber and being fitted into and held in the metallic head of a key by the suction of the cup.

3. In a Wind musical instrument with a key head, a pad for the keys thereof comprising a pouch shaped body filled With air, and vacuum means to hold said body in the key head.

4. In a Wind musical instrument with a key head, a pad for the keys thereof comprising a rubber pouch shaped body filled with air, and vacuum means to hold said body in the key head.

5. In a Wind musical instrument with a key head, a pad for the keys thereof comprising a rubber pouch shaped body con taining air and vacuum meansv to hold said body in the key hea-d.
